Realistically, Dreqs would likely be substandard compared to our own.
Simply put, when you're building things to be as efficient and compare way better to your competitors, it's probably gonna be better than the people who are designing things under orders.
However, we should also keep in mind that most FRAMEs we're using are secondhand and refurbished, while the Dreqs are in use by professional military personnel. They are pretty cheap, in terms of cost, but there are plenty of reasons why the OSU use it as their general-purpose FRAME!
Competition within the OSU is next to nonexistent - with the state controlling the businesses, they can pick and choose who will manufacture what and work with their suppliers to get the best bang for their buck.
Competition on the international level is another story, though...
